The preferred embodiment of this application N l-f. 3,45 fi ed fda h.2.8, 1, 35, for Detention window ripening. into United tates Letters Ptent No.2,13 7A37, datedNovember 2.2, 1938;,

The disclosure in Fig. 6 is the same as. Fig.13 as, originally filed in,my copending application Serial No.il. ,5,75 filed December 14, 19.36,for Detention, window and. method or glazing same, ripening intoUnitedgStatesLetters Patent No. 2,161,792, datedJune 13, W39;

The present'invention relates to a unitary pivctal bar about which aclosure swings outwardly on one side ofthe pivotal bar and inwardly onthe other side of the pivotal bar, which bar has arcuate surfacesadapted for engagement with a screen frame or any other particular meansoverlying the portions vacated by the. closure when swung into openposition. This has been accomplished by providing a barhaving verticaland/ or horizontal portions extending into ar-cuate por tions, which arcuate portions contact the screen frame. and may form a seat for theglazing.

In the drawings the reference character ill; indicates verticalmuntin'bars, as may best be. seen by referring to Fig. 1. The verticalmun tin bars it are interconnected by horizontal mu ntin bars 2. The onebounding thetop of he ventilating area, may havefa downwardly projectingflange or piece Hi welded thereto, so as to provide an abutment and awatershed for. the upperportion of the closure it, as may bestbe seen byreferring to Fig. 2. V p

The closure i3 is pivotally mounted to swing with a pivotal bar 22including an L-shaped portion 2d merging into a stem 28 constituting thestern of a substantially T-shaped portion having flanges one extendingupwardly and one extending downwardly along an arcuate path. One leg ofthe L cooperates with one of the flanges 39 to form a glazing channel 3L Aglass window pane 2a is mounted in the glazing channel or seat 34. p

The other leg of the L-shaped portion 24 merges, into an arcuate portion3%, the outer surface. of which has the same radius or different radius.Both arcuate outer surfaces bounding the flanges 30 are concentric. Thearcuate surface of the flanges 3Q engages a screen frame 40overlying'the outwardly swinging portionof the closure. The arcuatesurface of the portion 36 contacts a screen frame 42 overlying theinwardly swinging portion of the closure. Thearcuate surfaces ofportions 39 and 35 travel through a circular path and always remain inis disclosed in my copending application Serial contact with the screen.frames. In Fig. 3 the closure has been swung into open position withoutlosing contact with the screen frames.

In order to reduce corrosion the material of the pivotal bar may consistof aluminum, brass, stainless steel or any other suitable non-corrosivematerial. This prevents streaking of the screens placed on the underside of the closure. Instead of using non-corrosive metal for the entirebar, the bar may be electroplated with a suitable non-corrosive plating,such as chromium plating.

In the modification disclosed in Fig. 4, the L- shaped portion 50,together with the arcuate portion 52 are preferably made fromcomparatively soft material and the T-shaped portion 54 from hard toolresisting material. The stem of the T-shaped portion 54 is welded to oneleg of the L-shaped portion 50. In this modification both of the flangesof the T-bar cooperate with one leg of the L-bar to form a pair ofglazing channels', one above the stem and one below, as shown in Fig. 4.This arrangement provides a more solid glazing seat for the upper edgeof the glass. The tool-proof or tool resistant material used in theT-bar 54 deters severance of the pivotal bar, thereby increasing thevalue of the pivotal bar as a multi-functional bar, that is, muntin bar,pivotal bar, contact bar and detention bar.

In the modification disclosed in Fig. 5, the L- shaped bar has beeneliminated and instead a diagonal portion 60 has been used. Thisdiagonal portion 60 has one end merging into an arcuate portion 62 andthe other end merging into the stem I54 of the T-shaped bar. In thisstructure the flanges 66 of the T-bar cooperate with the stem thereof toform glazing seats.

In the modification disclosed in Fig. 6 a composite bar arrangement hasbeen utilized in a rail guard window assembly wherein the L-shapedportion 10 is provided with a downwardly projecting flange I2 along oneedge. The horizontal leg portion of the bar 10 is provided with aplurality of holes receiving round or other suitably shaped detentionbars I4, as more fully disclosed in my copending application Serial No.115,752, filed December 14, 1936, for Detention window and method ofglazing same. The rail bars or L-shaped bars I cooperate with thevertical detention bars 14 to form a detention guard suitable for use inpenal institutions or other places where there may be no ingress andegress of human bodies through the windows.

The T-shaped bar I8, preferably having tool resistant material embeddedtherein, may also be much harder or different than the material used inthe L-shaped bar 10. One leg of the L-shaped bar cooperates with theT-shaped bar to form glazing channels I6, receiving the window panes 80overlying the detention guard. In the modification shown, the channelabove the stem of the T-shaped member is shallower than the channelbelow the stem. This facilitates insertion of the window panes. This issimilar to the difference in the depths of the channels shown in Fig. 9,which will be explained more fully later. The same arrangement may beutilized in connection with Fig. 4, where the upper channel may, forexample, be much shallower than the lower, so as to accommodate theglazing. Thus, a duo-functional rail guard window assembly is produced.The stem of the T-bar I8 may be attached to the L-shaped bar in anysuitable manner. The angle bar I0 may be provided with an aperture 82that is aligned with the stem of the T-bar I8 and with the detention bar14. This aperture 82 is used as a pocket for receiving the weldingmaterial 84, which welds bars 10, I8 and when desired I4, into a unitarystructure.

Instead of using horizontal pivotal or composite bars, these may bevertical bars, or for that matter, diagonally disposed bars. In anyevent, the closure swings about the pivotal bar.

In the modification disclosed in Fig. 7 the pivotal bar includes abridge portion I00 having a downwardly projecting flang I02 and anupwardly projecting flange I04, forming spacing members for two pairs ofwindow panes I06. Each end of the bridging portion I00 merges into anarcuate flange I08. The radius of curvature of the outer surface of eachof these flanges has a common center. The ends of the pivotal bar arepivotally mounted in the frame of the window. The pivotal bar may extendhorizontally or vertically. The upper portions of the flanges I 08cooperate with the flange I04 to form longitudinal putty receivingpockets, which pockets are used as seats for the glazing I06 and theputty surrounding the edges of the window pane.

As the upper portion of the disclosure shown in Fig. '7 swings in theone direction and the lower portion swings in the opposite direction, itis necessary to provide screens II2 for the oppositely swinging portion,one located on the inside of the outwardly swinging portion and theother located on the outside of the inwardly swinging portion. The frameII4 of each screen H2 i preferably made from angle iron. The flanges IIBextending parallel to the glazing I08 abut the frame of the fixedportion of the window. The other flange II8 projects into theventilating area towards the swinging closure. The inwardly projectingflange adjacent the pivotal bar contacts the arcuate surface I08, so asto provide fiy-tightness whether the closure is in open or closedposition. This screen arrangement provides a screen that issubstantially flush with the outer surface of the fixed portion of thewindow, only the thickness of the flange H6 and the screen overlying thesame, extending beyond the outer surface of the fixed portion of thewindow. This results in a compact structure, neat in appearance,efficient, that can be easily constructed at a low cost. The doubleglazing results in low heat losses. The arcuate pivotal bar havingmerely the bridging portion I00 extending from the inside to the outsidealso reduces heat losses.

The frame bar I09 bounding the upper portion of the closure may beprovided with a downwardly projecting flange III which forms a partitionand putty receiving seats. As the glazing below the pivotal bar may beinserted any suitable distance up into the cavity between the arcuateflanges I08 and the downwardly projecting flange I02, the bottom framemember II5 has been provided with three upwardly extending flanges IIIcooperating to form glazing channels or glazing seats receiving theglazing and rigidly supporting the glazing in position along the bottom.

In the modification disclosed in Fig. 8 the pivotal bar I20,substantially circular in contour, is provided with a longitudinal slotI22 and a channel I24 located over the bridging portion I26. The slotI22 and the channel I24 form glazing seats. These seats support theputty surrounding the adjacent edges of the window panes. Outwardlyprojecting flanges I28 form stops, limiting the swinging movement of theclosure about its pivot. The main purpose is to permit the pivotal barI20 to be small in relation to the pivotal bar I40 has been shown.

- the closure swings.

. accepts window thickness. The swinging movement of the closure isarrested by the stops I28 abutting or engaging the inwardly projectingedges IIB of the screen frame. Thus, it is seen that the inwardlyprojecting edges I I8 of the screen frame constitute duo-functionaledges in that the edges contact the arcuate surfaces of the pivotal barand form a stop for the swinging movement of the closure.

Referring to the modification disclosed in Fig. 9, a composite bar hasbeen shown including a channel-shaped portion I30,which may be of castmaterial, or suitably extruded material, and. a sheet metal member I32substantially 3- shaped when inverted. The sheet metal portion I32includes a channel portion I34 merging into horizontal portions I36, asviewed in Fig. 9, terminating in arcuate flanges I38, The sheet metalportion I32 may be suitably attached to the channel portion I by weldingor in any other suitable manner. In this modification the channel inmember I32 is much shallower than the channel in member I30. Thispermits insertion of the glazing upwardly into the upper channel overthe lower edge, where it may be slipped into the lower channel. Byhaving the channels of unequal depth this facilitates the glazingoperation.

A pair of tool resistant members I35 is nestled between the arcuateportions I38 and the medial glass supporting portion of the assembly.The tool resistant rods prevent the easy severance of the pivotal barassembly in the event inmates should try to effect an escape through theventilating area.

In the modification shown in Fig. 10 a rolled This bar includes a pairof diametrically disposed arcuate surfaces I42. The center of curvatureof these arcuate surfaces coincides with the normal axis of rotation ofthe pivotal bar, about which axis The bar I40 also contains a pair ofglass supporting flanges I44, oppositely disposed with respect to thecenter of rotation of the pivotal bar and oppositely disposed withrespect to a common plane formed by corresponding sides of the flanges,this comm-on plane containing the axis of rotation.

The flange I44 positioned above the common plane, as viewed in Fig. 10,has two upwardly projecting flanges I46 and I48 cooperating to formsupports for the putty I50 surrounding the lower edge of the glass paneI52.

The opposite flange I44 positioned below the common plane, as viewed inFig. 10, has two downwardly projecting flanges I46 and I48 coopcratingto form supports for the putty I50 surrounding the upper edge of theglass pane I54.

The glass panes I52 and I54 are offset with respect to a vertical planeextending through the axis of rotation of the pivotal bar I45, as viewedin Fig. 10. This offset relation permits the use of a pair of screenframes IE0 and I62, positioned adjacent to, but on opposite sides of thevertical plane referred to above. The screen frames have been shown asL-shaped in cross sectional area. It is within the purview of thisinvention to utilize any other suitable type of screen frame. Likewise,the screen above the pivotal bar may be aligned with the screen belowthe pivotal bar if so desired. The offset relation of the glass panespermits of such a construction.

By shearing or cutting away the flanges I44 adjacent each end, theprojecting cylindrical core portion may be used as journals mounted insuitable hearings or holes in the fixed frame portion bounding the sidesof the ventilating area. The core portion and also the flanges may haveembedded therein non-annealable material, resulting in a tool resistantbar adaptable for use in detention and security windows. The upwardlyprojecting channel may in some installations be made shallower than thedownwardly projecting channel or vice versa, for the same purpose as setforth in connection-with Figs. 4 and 9, that is, to facilitate theglazing operation.

Although glass panes have been referred to throughout the specification,it is within the purview of this invention to use any other sheetmaterial that is translucent and/or transparent.

Although the preferred modification of the device has been described, itwill be understood that within the purview of this invention variouschanges may be made in the form, details, proportion and arrangement ofparts which generally stated consist in a device capable of carrying outthe objects set forth, in the novel parts, combination of parts and modeof operation, as disclosed and defined in the appended claims.
